I have touched on this once before in The Conversation Starter, but wine and dating are a good match (excuse the pun).
At the time Nicolla Greaves was organising occasional evenings on behalf of the WSET and they certainly caught some people's attention.
Nicolla is still with the WSET but has obviously decided that there is a future in matching wine tastings & education with the proper business of finding a soul mate (at least one who will hopefully understand your obsessional wine buying habits in years to come).
She and Nigel Littlewood, with a background in running bars, have set up an events company dedicated to this new aspect of the wine business (or is it a new aspect of the love business?).
I must say that the idea of a speed dating event terrifies me, but then being happily married (and maybe even above the usual age profile) I am not the target market. However I may have 1 or 2 young, single readers out there looking to put their hard won knowledge of wine to good use [and if it works out, do let me know in the comments]. I think the idea of having a topic of conversation like wine to kick off your first meeting is a good idea. Wine is a topic that says something about a person, whether they consider themselves a 'wine geek' (not that I expect ANYONE to use that term on the night) or 'novice', you can still have a view.
So, if you fancy it (!), why not check out their site and go along to one of their events (first one is on the 7th of April).
Oh, and if you've bought one of those wine notebooks it could easily double up for taking down his/her number or email address!
Good luck! After all, as they say, "it is all a matter of taste"
